SOLUTION

In a transformer, the voltage is linked to the number of turns in the winding. The voltage per turn is the same for both the primary and secondary windings because they share the same magnetic core and the same magnetic flux.

For example:

• If 1 turn in the primary winding produces 2 volts, then 1 turn in the secondary winding will also produce 2 volts.
• The difference between the primary and secondary voltages comes from the number of turns in each winding.

In a step-up transformer, the secondary winding has more turns than the primary winding. This increases the total voltage in the secondary, but the voltage per turn remains constant for both windings.

So, voltage per turn in the primary = voltage per turn in the secondary.
